Patented Dec. 20, 1 93 2 .fP'A-r NT v resiste- FFWE RAYMOND M. FROHDER,OF BROCKIJYN, NEW YORK ILLUMINATED FIREMANPs HELMET Application filedMarch 8, 1932. Serial: in). 597,577.

The object of my invention is toproduce a-lamp'that'canbe mounted'on thefront of a firemans helmet to'aid the fireman to proceed in the dark andthrough dense smoke to efiiciently rescue lives and save propertywithout unnecessary injury to himself in performing his required duties.

lVith the above and other objectsin vlew,

as will be brought out hereinafter, reference will be had to theaccompanying drawing forming a part of this specification and whereinFig. 1 is a vertical sectional view of the invention showing thespecific manner of applying the same to a firemans helmet, onlyfragments of the latter being illustrated;

Fig. 2 is a top plan View of the invention applied to a fragment of afiremans helmet. Fig. 3 is a view in front elevatlon of a liremanshelmet equipped with the invention. 1

Fig. i is a view in side elevation of a firemans helmet with theinvention applied, and

Fig. 5 is a sectional View taken on line 5-5 of Fig. 1.

In the drawing, reference numerals 15 designate the brim, 16 the crownand 17 the shield or emblem plate of a standard firemans helmet, and theemblem plate 17- may be supported at its top by the usual eagle head 18or otherwise asin standard constructions. Suitably mounted upon thebottom of the brim 16, preferably at the rear thereof, is

an electric cell 19, and upon the lower face of one side of the brim,preferably the right hand side so as to be within convenient reach,

is mounted a circuit breaker 20 of standard design. The crown of thehelmet is provided with conventional hollow ribs 21 in the channels 21aof which the conductor wires are laid and secured as by cleats 22. Anaperture 24 is provided through the front central portion of the helmetcrown including the front rib thereof, and the rear end of a conduitsection 25 is passed through this aperture. This conduit section isprovided with a saddle plate 26, welded or otherwise secured thereto andwhen in proper position, this saddle plate 0 embraces the outer surfaceof the helmet vided with a central contact 39 that is enlens 47 which issecured against the forward -rib 21 and closely conforms to'the curving"contour thereof. The extreme rear end of this conduit section isthreaded and receives thereon a washer .27 and nut 28, the latter takingthe threads of'the conduit section and clamping the section tightly inplace on the helmet, with an outlet opening 29 which is provided intheconduit aligned with the channel 21a. I The forward part of theconduit section 25 extends upwardly and outwardlylat an inclinationperpendicular to the part of the helmet crown to which it is attached,and before reaching the emblem plate '17 is bent substantiallyperpendicular to the said plate. The forward end of theconduit sectionis flanged at 30 to confine a coupling nut 31 on the conduit sections. I

An aperture 32 is provided in the central upper portion of the emblemplate, and

through this is inserted the-rear threaded end of a second conduitsection 33. This section is bent downwardly at a slight angle and isthreaded interiorly at its forward end to receive a threaded neck 34provided on therear of a reflector 35 as a socket to receive an electriclight bulb 36. The-rear end of the neck 34is flanged inwardly at 37 toretain a fibre disk 38,-the latter being pro-v gaged by the centralcontaction the light bulb, and the latter is threaded into the neckor-socket 34. One side of the battery is in direct circuitwith thesocket 34 through one strand of a'conductor 40, while the other side ofthe battery is in circuit with the cen-' tral contact 39 through thecircuit breaker '20. The conductor L0 in making this circuit follows theribs of the helmet as muchas possible in the channels of which it islaid,

and in passing through the helmet crown to the lamp, is threaded throughthe opening 29 which aligns with the channel of the front central rib21. i I 1 A lamp housing comprising a threaded rim 412, shoulder 43,body 44, neck 45- and base 46 'isprovided to receive and house theforward'end-of the conduit section 33, reflector 35, lamp 36 andappurtenances, as well as a edge of the rim 42 by a lens ring 48threaded onto said rim.

The outer rim of the reflector 35 has a. flange 35a that seats againstthe shoulder 43 to resist the pull of the coupling nut 31 when theconduit sections 25 and 33 are coupled together. In other words, thecoupling nut 31 and its associated washer 5O engage the inner face ofthe emblem plate 17 while the forward edge 35a of the reflector bearsagainst the housing shoulder 43, clamping the housing, whose rear edgeis shaped to the contour of the emblem plate 17, tightly against saidplate. At the same time, the

' coupling nut 31 draws the conduit section 25 tight against the conduitsection 33, providing a brace for the emblem plate and permittingelimination of the eagle 18.

All the wiring and electrical connections that may be affected by waterare enclosed either within conduits or within the helmet in a manner notto become short circuite'd.

Of course it will be understood that minor changes may be made as fallwithin the scope of the appended claims.

What is claimed:

1. The combination with a head piece hav-- ing a rigid crown andplate-like emblem member spaced therefrom, aconduit section passingthrough and secured to the crown, a second conduit section passingthrough the plate-like member, a coupling for the conduitsections, and alamp on the second conduitmember clamped against said plate-like memberby said coupling.

2. The combination of a head-piece having a rigid "ribbed crown andplate-like emblem spaced therefrom,a conduit passing through the crownand provided with a saddle embracing the exterior of one of the ribs ofthe crown, a clamping member on the conduit section within the crown forsecuring the crown between said saddle and clamping member, said conduitpassing through the plate-like member and a lamp on saidconduit a rigidcrown and plate-like emblem member spaced therefrom, a conduit securedto the crown and passing through said emblem member, a lamp housingbearing against the outer face of'the emblem member,a-reflector securedto the conduit and holding the'housing against the emblem member, andmeans engaging the rear face of the emblem member for clamping thelatter between itself and the lamp housing.
